Abstract (en)
The invention concerns a fire detector (1), comprising: an optical case (21); a light-receiving element (12) provided in the optical case (21); a received-light amplifying section for amplifying an output signal of the light-receiving element (12); and a fire determination section for determining occurrence of a fire when the amplified output signal is equal to or higher than a threshold value, wherein an outer surface of the optical case (21) has conductivity; and a signal-line retaining portion (41) for bringing a signal line (35) connected to an element substrate (31), on which the light-receiving element (12) is mounted, into contact with the outer surface is provided to the optical case (21) so that the signal line is not affected by noise present in the optical case ; and. an opening of the optical case is closed by an optical cover.
